１に押圧できるようにしている。A protection plate 16 is inserted next to the saw body 12 in parallel to the saw blade 15, and a groove 17 is formed in this protection plate 16. The groove 17 coincides with a cavity 18 in the saw body 12, forming therein sufficient space for a displaceable pin 19 with legs 20. This leg 20 is housed within the cavity 18 and can move within it, but is prevented from being dislodged there by a guard plate. The end of the pin 19 is somewhat tapered and projects into the hole 21 of the saw blade 15, so that the hole 21 of the saw blade 15 is secured to the pin 19. The saw blade 15 also has rectangular holes 22 into which the blade bolts 11 extend, connecting the saw blade 15 to the blade bolts 1.
It is set so that it can be pressed to 1.

れそしてカバー１０の内側に固定されている。One of these details 23 is provided with a tension adjustment screw 24 with a coarse thread, which tension adjustment screw 24 is journalled in a bearing and is fitted with a set screw 2 inserted in a bore 26.
It can be rotated by 5. This screw is a slotted screw (
It can be modified in various ways, such as a hexagonal screw (Fig. 2) or a hexagonal screw (Fig. 3). The coarse threads 27 of the tension adjustment screw 24 are contoured to match the tapered ends of the pins 19 that project between the threads when the cover 10 is installed. In this way pin 19
becomes a dog in the tension adjustment screw 24 and moves the pin 19 in the groove 17 when rotated, the blade 15 loosely supported on the attachment follows the movement of the pin 19 during setting. When the cover 10 is attached or removed, the pin 19 is engaged with or released from the screw without bothering the operator. A stop spring 2 is used as an auxiliary means for the tension adjustment screw 24.
8 is provided, the stop spring 28 being bent over the cam 29 and fixed inside the cover 10.
止めばね２８の端部はねじの一端に対して引つ弘られて

2. This preferably has the same dimensions as the nut 33 on the blade bolt 11 so that the same torque wrench can be used for all threads of the blade attachment. Furthermore, the deflection shaft 31 is bent away from the blade, making it easier to manipulate the screw. The variant of the set screw connected to the tensioning screw by an angle gear as explained above is also applicable as far as the device is concerned. Combinations of other types of tools, straight or angled outward from the cover, are also conceivable and applicable and do not limit the inventive concept as defined in the claims.
